PHP (foreign name: Php:hypertext Preprocessor, Chinese name: "Hypertext Preprocessor") is a common open source scripting language. The grammar absorbs the C language, Java and Perl features, is conducive to learning, widely used, mainly for the field of web development. PHP's unique syntax mixes the syntax of C, Java, Perl, and PHP's own creation. It can execute Dynamic Web pages more quickly than CGI or Perl. Dynamic pages made in PHP are compared to other programming languages, and PHP is executed in HTML (an application under the standard Universal Markup Language), which is much more efficient than CGI, which generates HTML markup entirely; PHP can also execute post-compilation code, Compilation can achieve encryption and optimize code execution, making code run faster.
Advantages of PHP
There are many benefits to applying PHP. Of course, the disadvantage is that PHP is not commercially supported because it is an open source project, and the resulting execution speed is slow (until PHP4). But PHP's mailing lists are very useful and unless you're running a popular site like Yahoo! or Amazon.com, you won't feel the speed of PHP being any different. At least I didn't feel it! Well, let's take a look at the advantages of PHP:
-Learning process
Unlike Java and Perl, you don't have to bury your head in more than 100 pages of documentation to learn how to write a decent program. As long as you know some basic grammar and language features, you can start your PHP coding journey. You can then go through the documentation if you are having trouble with the coding process.
PHP syntax with c,perl,asp or JSP. For those who are more familiar with one of these languages, PHP is too simple. Conversely, if you know more about PHP, you will be very easy to learn from several other languages.
You can get all the core language features of PHP in just 30 minutes, you probably already know the HTML very well, and you've even learned how to create a good-looking Web site with an editorial design software or by hand. Because PHP code can be easily added to your site, while you design and maintain the site, you can easy to join PHP to make your site more dynamic features.
-Database connection
PHP can be compiled into functions that are connected to many databases. PHP and MySQL are now a great combination. You can also write your own peripheral functions to access the database indirectly. With this approach, you can easily change the encoding to accommodate such changes when you replace the database you are using. Phplib is the most common set of base libraries that can provide general transaction needs.
-Scalability
As I said earlier, PHP has entered a period of rapid development. It may be difficult for a non-programmer to extend additional functionality to PHP, but it is not difficult for a PHP programmer.
-Object-oriented programming
PHP provides classes and objects. Web-based programming requires an object-oriented programming capability. PHP supports constructors, extraction classes, and so on.
-Scalability
Traditionally, the interaction of Web pages is achieved through CGI. The CGI program's scalability is not ideal because it opens a separate process for each of the running CGI programs. The solution is to compile the interpreter for the language that is often used to write CGI programs into your Web server (such as mod_perl,jsp). PHP can be installed in this way, although few would like to install it in a CGI manner. Built-in PHP can be more scalable.
